TFV8 Big Baby Light-Up Tank
24.5 mm Diameter
The LED lights are placed at the base of the tank, when you fire the device to vape, the LED will light up and change its color along with the color of sealing ring. Note: The output voltage cannot lower than 1.5V, or the LED won't light up. For example, if you have a core which is 0.1Ω, then according to the formula P= U^2/R you can get P= 1.5^2/0.1=22.5W You don't need to worry about this when the mod is in TC mode, for the out power can automatically adjust.
